Key Technical Advantages:

• High-Dynamic Pressure Compensation: Equipped with ultra-fast servo-control pistons, the system achieves instantaneous pressure regulation and flow correction under rapidly fluctuating loads. This significantly minimizes overflow losses, drastically improving the stability of heavy-duty machinery.

• Wear-Resistant Piston-Block Assembly: The cylinder block and pistons utilize high-grade ductile iron and specialized bronze friction-pair alloys. Precision honing processes ensure exceptional wear resistance and high-pressure durability, maintaining volumetric efficiency over extended lifecycles.

• Low-Noise Port Plate Design: The shape of the pressure transition grooves in the port plate is optimized to dampen fluid shock waves during the high-pressure commutation phase. This results in significantly reduced noise, perfect for high-precision manufacturing environments.

• Heavy-Load Bearing System: The core drive shaft is supported by high-capacity tapered roller bearings capable of simultaneously managing the massive axial and radial forces generated by high-pressure operation, ensuring structural stability under extreme loads.

Application Areas:

• Construction Machinery: Main system drives for excavators, drills, cranes, and skid-steer loaders.

• Industrial Manufacturing: Hydraulic power units (HPU) for automated presses, injection molding machines, and industrial actuators.

• Marine & Mining: Winch drives, anchor handling systems, and auxiliary power for surface mining equipment.

• Municipal Equipment: Hydraulic cores for sanitation and emergency rescue vehicle machinery.

Expert Maintenance Tips:

• Pre-fill & Bleeding Protocol: Before startup, always pre-fill the pump casing with clean hydraulic fluid through the top case-drain port. Never dry-start. Run the system at low load for 5-10 minutes to bleed all trapped air, preventing cavitation damage.

• Fluid Cleanliness Standards: Given the precision clearances, fluid must be maintained at ISO 4406 18/16/13 or better. We strongly recommend a 10μm or finer pressure-line filter to protect the servo-control valves from particulate-related jamming.

• Case Drain Monitoring: The case drain line must be routed directly to the reservoir below the oil level, with sufficient diameter to prevent backpressure. Excessive case pressure will damage the drive shaft seal, leading to catastrophic oil leaks.
